The present invention relates to a hot water device used for drying and heating systems of various industrial facilities, such as drying of waste containing a large amount of water such as barns, food waste, sewage sludge, and drying after painting various coating materials. The inside and outside surfaces of the heat exchanger are coated with a mixture of teflon and ceramics to form a plurality of heating elements, each of which has a coating layer, fixed horizontally before and after the heat exchanger, and by using a frame and a bracket inside several heating elements, each near infrared lamp Water is circulated using the heating means installed to improve the absorption of near-infrared radiation emitted from the near-infrared lamp to maximize the heat dissipation effect of the heating means, and the circulation of the water by the circulation pump is smoothly supplied. It increases the amount of water and radiates heat radiated more effectively. It is to provide a hot water device using a heating means in which a near-infrared lamp which doubles the heat exchange performance by allowing it to be transferred at a rate.

In general, a hot water device using near infrared rays is heated to the outside through a method of heating a pipe through which heat-absorbing fluid passes from the outside to near infrared rays and a pipe having a built-in near infrared lamp (= having the same function as the heating element of the present invention). Many methods such as heat generation is used.

Since the heat exchange is performed by radiating NIR directly to the pipe from the outside, the heat efficiency is extremely low in a primitive way, so the NIR lamp is installed inside the pipe to heat the pipe and circulate the water to the outside to circulate the water. However, the trend of using the method of heating is mainly to increase the surface area in order for the internal and external heat exchange to occur smoothly, and the near-infrared heat source is radiated inside the pipe to generate radiant heat. The degree of absorption to increase the heat of the pipe while minimizing the reflection of near-infrared rays and the arrangement of the pipes to maximize the heat exchange performance while facilitating the flow of water from the circulating pump were also very important tasks.

As an alternative to solve the above-mentioned problems, a method in which a tissue radiates near infrared rays to a fine pipe has been developed so that heat exchange is well performed. However, near infrared rays are not absorbed well and reflected inside the pipe, so that the thermal efficiency is low. Almost the same efficiency as that of the heater is generated, and the hot water device with the circular pipe zigzag structure decreases the heat exchange performance due to the flow resistance and the vortex generation. However, when a small number of circular pipes are installed, the water does not stay for a long time and is discharged immediately. Therefore, the heat exchange time is short, resulting in a decrease in heat exchange performance.

The present invention is to create a new configuration to solve all the problems of the conventional hot water device as described above, the present invention is communicated with the external circulation pump inside the main body is installed in communication with the heat exchanger upper part of the heat exchanger and the water supply In the hot water device consisting of a tube, the heat means is composed of an elliptical shape inside the heat exchanger and a heating means in which a near-infrared lamp is built-in inside the heating element in which a near-infrared absorption coating layer made of a mixed solution of teflon and ceramics is formed on the surface of the heat exchanger. It consists of several fixed horizontally in front and rear, and the front and rear of the heat exchanger by installing a plurality of support frames integrally formed with a fixed bracket fixed to the near-infrared lamp fixed to the inside of the heating element installed inside the heating element with a clip at the end of the near-infrared ray emitted from the near-infrared lamp Improves absorption to minimize the heat dissipation effect of heating elements The heating means by which the radiated radiant heat is transferred to the circulating water more efficiently and doubles the heat exchange performance, and the heating means in which the near-infrared lamp which maximizes the amount of water by maximizing the amount of water by smoothly proceeding the water supplied by the circulation pump The present invention has been completed with the technical problem of devising in providing a hot water device used.

First, when the external power is supplied to the hot water device 1, the circulation pump 6 is operated, and at the same time, some power is supplied to the near-infrared lamp 44 of the heating means 4 by the wires 46 to generate the heating element 42. Near-infrared rays are radiated into the inside, and the radiated near-infrared rays are generated by the near-infrared absorption coating layer 43 coated on the surface of the elliptical heating element 42 mainly made of aluminum, stainless steel, copper, etc. having high thermal conductivity. Most of the heat is absorbed to generate radiant heat, and the radiant heat is radiated more efficiently by the heat radiating protrusion 41 of the heating element 42, and is supplied to the heat exchanger 5 by the water supply pipe 7 by the circulation pump 6.
